How can I customize an ap report to my needs

Hello there, arr.

Thanks for turning to the Community for support. I want to ensure you can run a report with Accounts Payable (A/P) in your QuickBooks Online (QBO). 

There are report options for accounts payable in QBO - the Accounts Payable Aging Summary and the Accounts Payable Aging Detail. Here's how to view them and customize the data:

1. Click the Reports tab from the left menu.
2. Enter Accounts Payable in the field and choose from the generated options.
3. Select the gray Customize button in the top right corner.
4. You can choose Filter and place a checkmark on what you'd like to view.

However, you can filter by Customer when running accounts receivable reports using the same steps listed above. 

You can refer to the following articles for more information about filtering a report to get the data you need and saving it with its current customization settings: Customise reports in QuickBooks Online.

You can always count on us if you have other concerns or inquiries about your Accounts Payable reports in QuickBooks. I'm always here to make sure that everything is taken care of. Have a great day.
